TLDR: National government requires hotels to file paperwork to report foreign guests. Many budget hotels refuse foreigners to avoid it.
I was in Osaka for one night in 2001 and wanted to stay at a coffin hotel. They wouldn’t let me check in. Hadda stay at a tourist hotel instead, which was just like every other hotel I’ve ever stayed in. I was sad. :(
After a heavy night out in Okayama in 1992, friend and I stayed in a capsule hotel one night (the kind with lots of signs in the lobby and near the baths saying “no tattoos”). Nice having my own cozy snug, even saw a few minutes of squeaky porn on the in-built TV before I passed out.
The next morning we had to check out. But I was still so messed up from the night before, almost immediately had to check into another place, a regular hotel room, and lie down. I can’t tell you how much it made my poor hungover head spin every time I opened my eyes and saw that the ceiling was so far away!
- Adjustment time to being in a capsule: 0 hours, 0 minutes.
- Re-adjustment back to ‘normal space’: at least 8 hours.
because they suck
